Stainless Steel

Symbol for hygiene and high-quality material

"Only the consistently high chemical and mechanical resistance of stainless steel ensures consistently reliable quality, hygiene and aesthetics." Stainless Steel Information Point (ISER)

For more than 40 years, we have been processing stainless steel for a wide variety of applications. Benefit from our experience and our know-how.

Durable and low maintenance

Stainless steel has many advantages: corrosion-resistant, long-lasting, hygienic, environmentally friendly, resilient, temperature-resistant, wear-resistant and low-maintenance.

Using stainless steel will result in a very long life compared to mild steel on account of its great resistance to corrosion. Structures made from stainless steel will last many times the normal life. Stainless steel is probably more expensive to buy in the beginning. It is usually cheaper in the long run since it lasts for a long time and there is little or no maintenance and repair costs.

The quality of stainless steel depends on the professional and competent processing of the material. A long-standing, constantly expanding expertise and its consistent implementation, a highly motivated team and a modern machine park ensure that you profit from the advantages of stainless steel also economically.


Pickling and passivation of stainless steel

The corrosion resistance of stainless steels is based on the so-called "passive" oxide layer on the stainless steel. After the processing of stainless steel, this passive layer is damaged and the stainless steel can corrode.


Permanent corrosion resistance

Durable corrosion resistance requires the right material selection as well as proper design and processing. When processing stainless steel, for example by grinding or welding, this passive layer is damaged and stainless steel can corrode in this condition. In order for the passive layer to form again, stainless steel must be pickled and passivated after processing.

For the pickling of stainless steel, a mixture of nitpeter and hydrofluoric acid is usually used in order to remove the starting colors of welding constructions. At the same time, the nitric acid supports the more rapid passivation of the stainless steel. Thus, the passivation time can be reduced from about 10 days to about 1 day. 

For this process, we have built a large pickling and passivation plant with its own sewage and neutralization plant. The wastewater is thus purified, passed into the sewer with a neutral PH value, and the contaminated sludge is disposed of in an environmentally manner.

Meeting the highest hygiene standards

Hygiene, durability and resistance to scratches

The hard and homogeneous nature of stainless steel surfaces makes it possible to meet the highest hygienic standards. Stainless steel is characterized by a particularly smooth and inert surface, which is also scratch and abrasion resistant. Thus bacteria, germs and other impurities can not adhere to the surface. At the same time, migration - the process of transferring a chemical substance to another material - is minimized.

Hygiene is of utmost importance, wherever food and beverages, medicine and pharmaceuticals are produced, prepared or processed. Stainless steel has a proven record of success in these areas where sanitation and ease of cleaning are so important.


Advantages of Stainless Steel


Stainless steel is easy to clean and with only minimum maintenance, stainless steel can be maintained in the as-new condition for decades.


The homogeneous nature of stainless steel with its exceptionally smooth and inert surface ensures the highest hygienic standards.


Stainless steel has a better energy and resource balance in production than other materials and is 100% recyclable.


When life cycle costs are considered, stainless steel is technically and economically the best solution.
